2024-2025 Large Whale Season Summary
March 24, 2025
We have two separate efforts focusing on cetaceans off the coast of Virginia. The first is our Offshore (Outer Continental Shelf) Cetacean Study, which focuses primarily on deep diving odontocetes like sperm whales. The second effort is our Nearshore and Mid-Shelf Baleen Whale Monitoring Project.

Large Whale Action in the Mid-Atlantic
January 30, 2024
After a relatively slow start to the 2023-2024 large whale season, things are picking up here in the Mid-Atlantic. Last week was the busiest we’ve had so far this season for several of our projects as well as adjacent colleagues.

Aerial Surveys of Marine Mammals Conducted in the Inland Puget Sound Waters of Washington, summer 2013 – winter 2016
Project Objectives
1) Conduct aerial surveys during four seasonal periods within the inland Puget Sound Survey Area to assess potential differences in seasonal distribution, numbers, and behavioral state patterns of marine mammals; 2) Collect data to estimate densities of marine mammals in the inland Puget Sound waters for species with sufficient sightings; 3) Estimate abundance for each marine mammal species seen an adequate number of times; 4) Document the distribution and habitat use of each species observed; 5) Document and describe behaviors seen without performing focal follows.

Estimation of Received Levels of MFAS and Behavioral Response of Marine Mammals at PMRF
Project Objectives
Further our understanding of the Monitoring Questions: 1) What is the occurrence and estimated received levels of MFAS on 'blackfish', humpback, minke, sperm and Blainville's beaked whales within the PMRF instrumented range? and 2) What, if any, are the short term behavioral responses of 'blackfish,' humpback, minke, sperm and Blainville's beaked whales when exposed to MFAS/explosions at different levels/conditions at PMRF?

Long Term Acoustic Monitoring of Marine Mammals Utilizing the Instrumented Range at Pacific Missile Range Facility (PMRF)
Project Objectives
Improve understanding of the long term trends in occurrence of marine mammals (e.g., minke, humpback, fin, Bryde's, Blainville's) on the PMRF range. Examine what, if any, acoustic and physical behavioral responses occur to Navy activities.
